8687Re: [rootsradicals] lowest rear gear
- Apr 2, 2009Perhaps, one of the outer cable housings is messing you up. If you
are using the newer style ("JagWire" is one brand) derailer housings
that is made of a linear arrangement of wires, perhaps one of the ends
needs a ferrule, otherwise the wires can get pushed out and
interfere. Or, if it is old-style (like a brake cable) then maybe it
was clipped in a way that crimped it so it pinches the inner cable.
Either of these would add lotsa friction.
Because of the long cable runs, simple grease (if you grease your
cables) can also slow down your shifts (there are good reasons to
grease cables in Boston if you ride in the winter).
Or have these already been considered? (These are problems that have
actually happened to me or bikes that I have worked on.)
